Been flying stock with 900 mah and aeronaut carbon prop 8x6 and aeronaut spinner.,. fiberglassed the tail and put lemoN rx gyro...super fun... I would say 65-75 mph .. not bad for $100 RTF , though this can take more speed .

I built another with microdan 2900kv on 3 cell and 4 cell on 5 x5 and 5.25x4.75 + 45 amp esc 600+ watts makes it a pylon racer close to molded ones... glassed the tail with CA + FG

Got this foamy used from a local JET flier, then I proceeded to re-paint the whole plane..add scale weathering, bomb racks, tail hook , and finally added Mr RC sound system in a 1100mm plane..thats right.... flies on 4 cell now... Dinogy Orange pack.,...awesome flier and gets everyones attention...parts are super scarce for this plane..so its mostly on shelf now..

Hard to store these one piece planes, I don't like to put together big jets and planes at the field and redo the connections.,.,. I always like one piece and just slide in battery with minimal set up. Now this limits me by a lot .. may be a bigger house and truck

Bought this plane in a crashed/damaged state from RCG member couple years ago.. finally fixed it up.. and had it maindended it last weekend and couple speed run flights today... based on Doppler from the earlier Reverb, on mega 16fd , we are guessing this around 165-170 mph... ... the launch is the tricky part once figured out..then its blistering speed time with awesome eerie sound of a composite wing.
makes my jets lot slower..seeing this fly 165+ mph....
lands around 45- 55 mph. without spoilerons.

Last year I did buy off here a damaged fusion 400 and I kinda rebuilt it totally and today I had a chance to fly..OMG with 400 watts this thing hauls..I am using a HK 5x5 Prop which I will change to APC for next flight...loving it.
